MECHANICAL MOVEMENT.

Specification of Letters Patent.

Application filed July 6, 1911.

Patented May 14, 1912. Serial No. 637,103.

To all whom it may 00ncern Be it known that I, LOUIS JUDnLsoN, :1 citizen of the United States of America, residing at 159 -West Twenty-fourth street, New York city, in the county and State of New York, have invented certain new and useful Improvements in MechanicalMovements, of which the following is a specification.

My invention relates to a new mechanical movement whereby the direction of rotation of a revolving body may be reversed as frequently as desired within a given period of time.

The object of my invention is to provide simple and efficiently operating means adapted to reverse the direction of rotation of a revolving or rotating body without stoppage of the latter and without any resulting loss of power.

Other objects and advantages of the invention will be more fully hereinafter explained and defined by the appended claims.

My invention is susceptible of embodiment in several forms, and to enable the principle and operation thereof to be clearly understood, I have attached hereto a sheet of drawing illustrating two concrete forms of the invention in lts application to a washing machine.

In the drawing Figurel is a top plan view of one form of the invention; Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 and looking in the direction of the arrows; Fig. 3 is a top plan view of a modified form of the invention; and Fig. 4 is a view of a detail more fully hereinafter referred to.

Before proceeding to a detailed description of the several views of the drawing, 1' deem it necessary to state that the invention may be applied to a great variety of uses wherein the object to be attained is the reversal of direction of rotation of a revolving or rotating body, and while I have herein shown and will hereinafter describe the application of the invention to the cylinder of a washing'machine, I desire to make it clear'that the invention is not so limited in scope, and the particular application has been chosen for illustrative purposes to render the principle, construction and operation readily understandable.

Referring now in detail to the drawing and more particularly toFigs. 1 and 2 thereof, it will be noted that I provide a suitable frame, consisting of the end bars 10, side bars 11 and legs 12, as a support for the operative parts of the structure. Revolubly mounted in bearings 13 formed in or on the side bars 11 is a shaft 14 to which is fixed the gear wheel 15 interposed between the source of power and the body to be driven in reverse directions. The gear wheel 15, which forms one of the important constituent features of my invention, has a portion or seg ment of its periphery removed as indicated at 15 in Figs. 1, 2 and 4, and is provided on each of its lateral faces, at or near its periphery, with a preferably continuous se ries of gear teeth, 16 and 17, of suitable pitch and height. Secured to the wheel 15, at the cut out portion 15, is a double-armed arcuate guide 18, having the oppositely projecting arms 18 arranged in pairs as shown. The guide 18 cooperates in causing reversal of the direction of rotation of the gear wheel.

15 and the body driven from the latter. One

of the end bars 10 is provided with a bearing 19 through which passes, longitudinally of the supporting frame, the shaft 20 carrying the belt pulley 21 by means of which said shaft is driven from any suitable source of power not shown. In the form of invention illustrated in Figs. 1 and 2, the shaft 20 has secured thereto a pair of spaced rotatable members or disks 22 substantially circular in shape and each provided with the lateral flanges 22 of greater diameter than the disks themselves. Each disk is supported by, and adapted to turn in, upper and lower straps or supports 23 and 24:. secured to the frame by means of screws 25 or the like, the arrangement being such that the flanges 22 lie outside of the straps and frictionally contact with their lateral surfaces. To insure uniformity of revolution of the disks 22, I preferably connect one flange of each disk to a rigid partial sleeve or cylinder 26 by means of nails or screws 27. At the end opposite that carrying the pulley 21, the shaft 20 is threaded to receive a nut 28 for the purpose of preventing the shaft from shifting longitudinally in its bearings. Projected through the disks 22 and bearing therein eccentrically to the driving shaft 20, is a countershaft 29 provided intermediate its ends with a gear wheel adapted to mesh with, and be driven from, a gear wheel 31 keyed to the shaft 20. The counter shaft 29 projects radially of the gear wheel 15, and fixed on the shaft 29 near that end thereof which is in proximity to the gear wheel 15 is a pinion 32 adapted to mesh alternately with the teeth 16 and 17 on the wheel 15. At its extreme end, adjacent the pinion 32, the shaft 29 carries a friction roller 33 revoluble on the guide 18 as the pinion is shifted from one side to the other of the gear wheel 15. At one of its ends the shaft 14, upon which the gear wheel 15 is fixed, carries a spur gear wheel 3 1 in mesh with a smaller gear wheel 35 fixed on the shaft 36 of the body to be driven, in this instance this driven body being represented as the fragment, 37, of the cylinder or drum of a washing machine, wherein the clothes are revolved with the drum first in one direction and then in the other. The gearing (EM-35) interposed between the gear wheel 15 and the cylinder 37 may be such as to revolve the cylinder 37 any given number of times for each revolution of the gear wheel 15, the arrangement in the drawing being a reducing gear connection by means of which the cylinder makes approximately four revolutions for each complete revolution in the opposite direction of the wheel 15.

Referring to the modified form of the invention shown in Fig. 3, it will be noted that the fundamental features are in all respects like those in the form of invention first described and differs therefrom merely in de tails. In this modified form the cylinder 37 is carried directly by the shaft 14 and consequently revolves in the same direction and at the same speed as the gear wheel 15. The construction illustrated in Fig. 3 is adapted for a lighter machine than the form first described, and there is but one disk 22 employed instead of two as in Figs. 1 and 2.

Corresponding reference characters designate like parts in all the figures of the drawing.

The invention will be clearly understood from the foregoing description of its construction, read in connection with the following statement of its operation :WVhen power is applied to drive the shaft 20, rotary movement will be imparted to the counter shaft 29 through the gear 3031, causing the pinion 32 to revolve. The pinion being in, mesh with either the gear teeth 16 or 17, the gear wheel 15 and shaft 14 will be rotated, thus revolving the drum 37 either through the reducing gear connection of Figs. 1 and 2 or the direct shaft connection of Fig. 3. The gear wheel 15 and cylinder 37 continue to revolve simultaneously in one direction so long as the pinion rolls on the gear teeth on one side of the wheel 15, but as the pinion reaches the end of one series of teeth, the friction roller 33 encounters one of the arms 18 of the guide 18, the friction roller traversing one of the guide surfaces 18 from one end thereof to the other by which action the shaft 29 and parts carried thereby, and the disks 22 are caused to make one half of a revolution about the shaft 20 as a center, and the pinion 32 is then put into mesh with the teeth on the other side of the wheel 15, the latter caused to revolve in a reverse direction and as a consequence to reverse the direction of rotation of the drum 37. In Fig. 41 the arrow inclicates the movement executed by the pinion 32 from the full line to the dotted line position, and in Fig. 1 the pinion 32 is shown in dotted lines in full mesh with the teeth 17 after it has been moved by the guide 18 from the teeth 16 to the teeth 17 of the gear wheel 15.

Vhile I have herein fully shown and described, and have pointed out in the appended claims certain novel features of construction, arrangement, and operation, which characterize my invention, it will be understood by those skilled in the art that various omissions, substitutions, and changes in the forms, proportions, sizes, and details of the device and of its operation, may be made without departing from the spirit of my invention, the scope of which is defined by the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a mechanical movement, the combination with a main gear wheel having gear teeth on both of its lateral faces, of a pinion for revolving said main gear wheel, a shaft upon which said pinion is carried, a driving shaft from which the pinion shaft is driven, rotatable members arranged one in front of the other through which both shafts project, supports in which said rotatable members rotate about their centers and means whereby the pinion and pinion shaft are moved about the driving shaft as a. center from one side to the other thereof whereby the pinion is moved from one side to the other of the main gear wheel to reverse the direction of rotation of the latter.
